Check Digit Verification of cas no

The CAS Registry Mumber 943539-83-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,3,5,3 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 943539-83:
(8*9)+(7*4)+(6*3)+(5*5)+(4*3)+(3*9)+(2*8)+(1*3)=201
201 % 10 = 1
So 943539-83-1 is a valid CAS Registry Number.

Catalytic and asymmetric Friedel-Crafts alkylation of indoles with nitroacrylates. Application to the synthesis of tryptophan analogues

Sui, Yong,Liu, Li,Zhao, Jun-Ling,Wang, Dong,Chen, Yong-Jun

, p. 5173 - 5183 (2007)

An asymmetric Friedel-Crafts alkylation of indoles with nitroacrylates catalyzed by chiral (4R,5S)-DiPh-BOX (L1)-Cu(OTf)2 complex (10 mol %) has been developed. The reactions provide tryptophan nitro-precursors in moderate diastereoselectivitie
